1, shotcrete manipulator is a kind of large intelligent robotic arm shotcrete machine, also known as concrete shotcrete trolley. The shotcrete manipulator is a special equipment that integrates the functions of self-walking, concrete pumping, robotic arm spraying and remote control, and has the characteristics of high intelligence, less spraying dust, less spraying rebound and high spraying surface strength.

2. The shotcrete machine operator keeps the operator away from the high dust environment and reduces the occupational hazards. It is suitable for various working environments and widely used in shotcrete support engineering.
